15. Board up large vent holes that have been created from the inside of the
attic with scrap plywood, etc. For example: If wind driven turbines have been
installed in the roof, simply board up the interior hole and leave the roof alone.
The turbine may still rotate, but it will not draw out air.
16. Disconnect the power to any installed power ventilator and board up the
hole from the inside of the attic. This leaves the roof appearance as is but renders
the ventilator inoperative. It also closes up what is an excess passive opening in the
attic.
17. Ventilation should be reduced down to what the house was built with.
Again, the rule of thumb is 1 sq foot for each 350 sq ft of attic area.
18. The actual cubic air space inside of the attic is not important. It is the
roofÕs surface area and being able to draw the air off of the roofÕs interior through the
PCS1 heat transfer coil that is. Air itself does not hold much heat.
19. If a radiant heat barrier has been installed onto the roofÕs interior, it must
be removed for effective operation of the PCS1.
20. If a radiant heat barrier has been installed on the ceiling area, it can be left
as is since it does not affect the operation of the PCS1. NOTE: radiant barriers work
to keep the attic heat from radiating into the home. The PCS1 solves this problem
by taking the heat and placing it into the swimming pool. The PCS1 removes the
heat load from the ceiling of the house.
21. The PCS1 can function as an attic ventilation fan by unplugging the
bypass valve and turning the LX220 to O N [manual override] and opening all
outside attic vents. This can be useful in some instances.
22. Make sure the attic temperature sensor is out of the air stream and is
mounted near the peak of the roof.
